Scerpico is dead on. She is the one witht the obligation to the OP. The dudes may be devoid of tact but not doing anything to him, they are just getting some free *****. Dude wreck her life by moving on to better things. I assure you that the lifetime of having to pay you child support and drive both ways to see the kids in a supervised areana will be long standing torture for her. Never even mention it to her again, just move on it and keep her on her ****ing knees the rest of her life.
Don't be a casualty bro. We have enough idiots locked up. Machismo is good for somethings, but getting oyu taken out where she gets the kids, or some releative gets them is a losing proposition for everyone. You having a life after her with your kids and another appreciative women will forever be a reminder of her sins against you bro.
